Solved Problem when Direwolf20 server was updated (5.2)

[CharlieBros]

Hi!,
Today I was going to launch FTB Direwolf20 in my PC, when I noticed that a new version (5.2) come out.
I immediatly downloaded and uploaded the new version to my private Minecraft server (host by MCProHostings).
When I tried to start it, I found the following problem in the console:

This is a complete paste of the crash report: http://pastie.org/6466573

I see that the problem is Xycraft, I thinked that the Xycraft included in the modpack was corrupt, but even changing it for the one downloaded from the Xycraft site it make the same error.
I also tried updating forge, doesn't work.

Are you using MCPC+ by chance?

You didn't move the new ftbserver.jar over when you updated.
Direwolf20 Modpack v5.2 is using Minecraftforge-universal-1.4.7-6.6.2.534
Your log says it is still using Minecraft Forge 6.6.1.524

Thanks BuzZ, I must say that I already uploaded the new jar and didn't work, but I downloaded again the modpack server, re-uploaded the jar, and now works flawlessly.
Ronan, I don't even know WTF is "MCPC+".

Greetings.
